I have a question i have a 3.11FW psp im gonig to buy lumines and pick up a 4GB memory card for downgrading (i have the wire). When i dongrade it to 1.50 i can play downloaded games? If so, whats so big about the Custom Firmware? what does it do? I can install custom fw on my newly downgraded from 3.11>1.5 PSP right? i dont need to downgrade it to 1.00? Would you reccomend the latest OE Firmware? What is DevHook? Why is it better/worse than custom firmware? I need to have a PSP on 1.00 or 1.50 to use devhook? or should i just not bother at all with it and stick to custom FW? What is XMB? what is so good/bad about it? What about Custom Icons? im fine w/ the ones i have right now, so i guess i couldn't care less about custom icons.. id really appreciate any suggestions and dont call me a noob i am going to establish the fact that ys, i am a noob when it comes to PSPs.
